摘要
对目前常用的递减类型判断方法(图解法、试凑法、曲线位移法、二元回归法、牛顿迭代法及递减曲线标准图版法等)进行了研究,并从J.J.Arps产量递减理论及油田实际生产数据出发,对各种方法进行了评价。作者认为在对油田进行产量递减类型判断时,不能单纯用一种方法进行判断,应将多种方法相互结合,相互验证,采用综合判断法进行判断,从而提高判断的精度,使其更加科学,更加切合实际。并通过油田实例,说明综合判断法具有较好的可行性。
Methods in common use to determine the type of production decline, such as graphical method、cut and try method、curve shift method、two variable regression method、newton iteration method、the standard plate method of the decline curve , are studied in this paper , the author appraised the different methods to determine the type of decline based on the study of J.J.Arps's production decline equations and the practical data。The author put forwards synthetical method to determine the type of decline in order to be more suitable to the fact and improve the accuracy. The living example shows that this method has a high accuracy in decline ,which is practical in oil field.
